CTSP Tree Climbing and Rigging Safety Flashcards

When rigging a limb for controlled lowering, what is the most critical factor to evaluate?

Answer: The estimated weight of the piece relative to the rigging system's working load limit

The weight of the piece being lowered must not exceed the working load limit of all rigging components involved to prevent catastrophic failure.

What is the purpose of a running bowline knot in tree rigging operations?

Answer: To create a noose that tightens around a limb for controlled lowering

A running bowline forms a sliding noose that cinches around a limb, allowing it to be secured and lowered in a controlled manner.

Which condition requires a climbing rope to be immediately removed from service?

Answer: Core damage, glazing from heat, or cuts visible in the rope sheath

Core damage, glazing (heat damage), or sheath cuts indicate the rope's structural integrity is compromised and it must be retired immediately.

In tree climbing terminology, what is a 'crotch' and how is it commonly used?

Answer: The union point where two or more branches meet, used as a natural anchor or redirect

A crotch is the junction where branches meet and is commonly used by climbers as a natural anchor or redirect point for the climbing line.

When using a mechanical ascender during tree climbing, what backup must always be present?

Answer: A secondary friction hitch or backup device on the climbing line

A secondary friction hitch or backup device is required alongside a mechanical ascender to prevent a fall if the mechanical device fails.

Which of the following correctly describes how to inspect a climbing carabiner before use?

Answer: Verify the gate opens freely and the locking sleeve is functional

A pre-use carabiner inspection must verify the gate opens and closes properly and that the locking mechanism functions correctly to prevent accidental opening.
